Right now we are using 5.1 but with the secuity problems where having (I work for a public school district). We are looking at getting ZenWorks to help with that problem... In fact on Weds. where going to another school district to see it in action. We did buy Zenworks when it 1st came out, but it was so new then support for it was for crap so we trashed it. And now that my boss has more or less put it in my hands now, that it might actually get used this time
